Abstract

A parallel 3D code for simulation of galaxies and protoplanetary discs is developed. The model includes dust, gas, gravitation and friction between dust and gas. The kinetic equation for dust particles is solved by PIC method. Gas dynamics equations are solved by FLIC method. In parallel implementation a domain decomposition technique is used where each subdomain is processed by a group of processors. Results of parallelization efficiency are presented.
